After a jury trial, Kamron Dehghani was convicted of four counts of various child pornography offenses. He appeals, arguing that the district court 1 erred in denying his motion to suppress, abused its discretion in failing to recuse at sentencing, and abused its discretion in imposing a procedurally flawed and substantively unreasonable sentence. For the reasons discussed below, we affirm.
1. BACKGROUND
In January 2006, a Kansas City, Missouri police investigation of child pornography-related messages posted to web sites led to an internet account registered at an address in Belton, Missouri. Detectives Maggie McGuire and Brian Roach visited the Belton address, which belonged to Kamron Dehghani and his wife. During the visit, with Dehghani’s permission, Roach removed a computer from the residence. After a forensic evaluation of the computer revealed child pornography, the detectives contacted Dehghani to arrange an interview. Dehghani originally declined to meet with the detectives, claiming that he suffered anxiety problems when traveling long distances. After the detectives agreed to conduct the interview at a police station close to his residence and at a time when his wife could drive him, Dehghani agreed to be interviewed.
The detectives’ interview with Dehghani began around 6:30 p.m. and ended approximately five and a half hours later. At the beginning of the interview, McGuire read Dehghani his Miranda 2 rights from a form. Dehghani read the form back to McGuire and signed it. Dehghani initially denied having any involvement with child pornography. At one point during the interview, Roach slammed his hand on the table and, in a loud tone of voice, told Dehghani that if he continued denying involvement, he would be arrested. Roach then told Dehghani he needed to get ready for the arrest by taking everything out of *719 his pockets and removing his belt and shoelaces. As Dehghani emptied his pockets, he told the detectives that they were correct when they earlier suggested that some people might be curious about child pornography because they had been abuse victims themselves. Dehghani stated that he was molested by his father and began to cry. After the detectives resumed questioning, Dehghani continued to deny his involvement with child pornography until the detectives confronted him with evidence from his computer, at which point he confessed. The detectives then prepared a statement reflecting Dehghani’s answers to their questions, which Dehgha-ni signed, and they allowed Dehghani to go home.
A federal grand jury indicted Dehghani on charges of publishing a notice to exchange child pornography over the internet, 18 U.S.C. § 2251(d), attempting to receive child pornography, 18 U.S.C. § 2252(a)(2), attempting to distribute child pornography, 18 U.S.C. § 2252(a)(2), and possession of child pornography, 18 U.S.C. § 2252(a)(4). Before trial, Dehghani filed a motion to suppress his statements from the interview. The district court found that Dehghani knowingly waived his Miranda rights and made his statements voluntarily. A jury found Dehghani guilty on all counts of the indictment.
While in custody awaiting sentencing before Judge Fenner, Dehghani attempted to send a letter to a newspaper that contained a threat to the judge’s life. The letter alluded to the location of the judge’s home and referred to his wife and stepson. The letter also included threats to assassinate President Bush, to plant bombs on city buses, and to poison the city’s drinking water. Dehghani also hatched an escape plot with another inmate in which they would use a sharpened toothbrush to subdue a female guard. After the threats and the escape plot, including the sharpened toothbrush, were discovered, Dehgh-ani filed a motion seeking the recusal of Judge Fenner, arguing that he would be biased because of Dehghani’s threat to the judge. Judge Fenner denied Dehghani’s recusal motion, explaining that Dehghani’s threat against him was an attempt to manipulate the criminal justice system and that Dehghani had no realistic ability to carry out the threat.
At sentencing, the district court calculated a total offense level of 39, including a two-level enhancement for obstruction of justice under United States Sentencing Guidelines § 3C1.1, and a criminal history category of I, resulting in an advisory sentencing guidelines range of 262 to 327 months’ imprisonment. The district court then sentenced Dehghani to 432 months’ imprisonment after finding that the advisory guidelines range did not fully account for the scope of Dehghani’s criminal conduct or the extent of his attempts to obstruct justice. Dehghani appeals, arguing that his statement to the detectives was involuntary and should have been suppressed, that Judge Fenner should have recused himself, and that the sentence was procedurally flawed and substantively unreasonable.
II. DISCUSSION
We first address Dehghani’s argument that the district court erred in denying his motion to suppress. Dehghani alleges that the detectives’ coercive tactics overcame his will and that his confession was, therefore, involuntary. “We review the district court’s factual findings for clear error and its conclusion regarding the voluntariness of a confession de novo.”
United States v. Brave Heart,
In support of his argument that his statement was involuntary, Dehghani contends that the detectives overcame his will by physically intimidating him, promising that he would not be jailed if he confessed, and questioning him after he had an emotional breakdown. The magistrate judge’s report and recommendation, adopted by the district court, made several factual findings that rebut Dehghani’s claims.

The court found that although Roach slammed his hand on the table and raised his voice, he did not physically intimidate Dehghani by, for example, raising his fists or using profanity. The court also found that the detectives never told Dehghani he would not be arrested if he confessed. The court additionally found that although Dehghani cried, he did not cry uncontrollably or appear disoriented. He did not confess immediately after crying; instead, he continued to deny involvement with child pornography until the detectives confronted him with evidence from his computer. None of these findings of fact are clearly erroneous in light of the detectives’ testimony.
See United States v. Hines,
Furthermore, there is no evidence that Dehghani was particularly susceptible to the detectives’ pressure. Dehghani appeared to be of at least average intelligence because his answers to questions were coherent, if not always truthful, and he displayed some understanding of the internet and file-sharing programs.
See, e.g., United States v. LeBrun,
Other factors also weigh in favor of a finding that Dehghani’s confession was voluntary. First, the detectives advised Dehghani of his
Miranda
rights orally and in writing. Dehghani waived those rights orally and in writing, and he never invoked any of his
Miranda
rights.
See United States v. Mendoza,
We next address Dehghani’s contention that the district court abused its discretion in denying his motion to recuse. We review the denial of a motion to recuse for abuse of discretion.
Moran v. Clarke,
In denying the motion to recuse, Judge Fenner concluded that Dehghani’s threat against him was an effort to manipulate the criminal justice system by attempting to obtain a different judge for sentencing. Judge Fenner explained that Dehghani did not “have the capacity by any stretch of the imagination to carry out” the threat against him. However, the court did find that Dehghani’s threats against jail personnel were serious and recommended that Dehghani’s transfer to federal custody be expedited. During sentencing, the court increased Dehghani’s advisory guidelines range and increased his sentence beyond that range partly because of Dehghani’s efforts to obstruct justice by threatening the judge, jail personnel and others. Dehghani contends that an average person would question the impartiality of the court because his threat against Judge Fenner appeared credible, the court’s findings regarding the seriousness of his various threats were inconsistent, and his ultimate sentence was based on the threat that formed the basis for the recusal request.
First, Judge Fenner’s finding that the threat against him was an attempt to manipulate the criminal justice system is amply supported by the record. Judges are not required to recuse themselves any time they are threatened.
See United States v. Gamboa,
Second, Judge Fenner’s finding that Dehghani’s threats against jail personnel were serious does not conflict with his finding that the threat against him was not. While in jail, Dehghani had fashioned a toothbrush into a weapon. Dehghani clearly had the ability to harm a guard in his immediate vicinity with such a weapon, whereas he had no ability to carry out his threat against the judge while in custody. The fact that Dehghani knew some details about Judge Fenner and his family, including the general location of his home, does not alter the conclusion that Dehghani had no ability to carry out the threat against him. Thus, there is no inherent contradiction between the two findings, and a fully-informed average person would not conclude that Dehghani’s serious threats against jail personnel showed that his threat against Judge Fenner was also credible.
Furthermore, Judge Fenner did not increase Dehghani’s advisory guidelines range for obstruction of justice under § 3C1.1 because of the seriousness of the threat against him but rather because of the seriousness of Dehghani’s attempts to manipulate the criminal justice system. An empty death threat can nevertheless be a credible attempt to manipulate the system.
See Holland,
Finally, Dehghani challenges his sentence, arguing that it was both procedurally flawed and substantively unreasonable. First, we consider whether the district court committed any procedural error.
Gall v. United States,
552 U.S.-,
Dehghani contends that the district court erred procedurally by failing to consider the § 3553(a) factors and by failing to sufficiently explain the basis for its chosen sentence. Although the 432-month sentence imposed by the district court was
*723
substantially greater than the advisory guidelines range, we disagree with Dehgh-ani’s arguments that it was procedurally flawed.
4
The record demonstrates that the district court considered the § 3553(a) factors, specifically mentioning the need to deter criminal conduct, to promote respect for the law, and to protect the public from Dehghani’s criminal activity.
See United States v. Walker,
We next address Dehghani’s contention that his sentence was substantively unreasonable because the district court allegedly failed to consider certain mitigating factors.

We review the substantive reasonableness of a sentence for abuse of discretion.
Gall,
III. CONCLUSION
For the foregoing reasons, we affirm Dehghani’s conviction and sentence.
Notes
. The Honorable Gary A. Fenner, United States District Judge for the Western District of Missouri.
.
Miranda v. Arizona,
. The Honorable Robert E. Larsen, United States Magistrate Judge for the Western District of Missouri.
. Although the district court used the term "departure” when sentencing Dehghani, the court's considerations clearly demonstrate that it actually imposed a variance under the § 3553(a) factors. However, where the ultimate sentence is reasonable, this type of conflation is harmless error.
See United States v. Miller,
. Dehghani also argues that the advisory guidelines themselves are substantively unreasonable because they violate the parsimony principle of § 3553(a) by creating unduly harsh sentencing ranges for child pornography offenses. This court has rejected that argument.
